This could have sparked tensions between Quonos and Earth, but ended up as a low-key bottle show with no impact on the series and nothing learned about the Klingons of this era (except we do see a Targ, which was a nice touch, even if the effects weren't convincing). Just another episode that dangles hope we'll see prequel elements without delivering. It was cool to see the new generation in their new uniforms against the familiar backdrop of a Klingon ship, though.
